MEKLER MEANS PREVENTING PASSAGE OF GAS THROUGHREFRACTO RY WALLS Filed July 23, 1930 Fatented Aug. 28, 1934 MEANSPREVENTING PASSAGE F GAS THBOUGH REFRACTORY WALLS Lev A. fielder,Chicago, 111., assignor to Universal Oil Products Company, Chicago,111., a corporation of South Dakota Application July 23, 193., SerialNo. 470,203 6 Claim. (UL 72-101) This invention relates to a means andmethod of" preventing the passage of gas into or out of a furnace or thelike through the refractory lining thereof, and refers specifically to amethod of so forming and so disposing the blocks, comprising the lining;with respect to each other as to leave spaces at a portion of thejoining surfaces of adjacent blocks which may be filled with a sealingor The utility, objects and advantages of my invention will be apparentfrom the accompanying drawing and the following detailed description.

In the drawing, Figure 1 is a fragmentary elevational view of a portionof a furnace roof or ceiling wherein my invention is utilized;

Figure 3 is a sectional elevational view of a suspended block forfurnace wall constructions embodying nrv invention;

Figure 4 is a front elevational view of the wall shown in Fig. 3;

Figure 5 is a sectional .view taken on the line 55 of Fig. 3; and

Figure 6 is a detail perspective of a refractory block which may beutilized in the construction of a furnace wall.

Referring in detail to the drawing, 1 indicates a furnace roof orceiling which may be constructed of concrete or the like. One flange ofeach of a plurality of beams 2 may be imbedded in the roof 1. The beams2 may take the form of l-beams, channel irons, or any other desirablebeam section. In the construction of furnace roofs or ceilings thesupporting roof is usually insulated from the secondary or insulatingre- I iractory roof, said insulation being accomplished by spacing therefractory roof from the supportingroof. Bythismeansanairspace3maybeprovided between the supporting roof 1 and the refractories.

It is common practice in the furnace art to suspend the refractoryblocks or tile from the supporting roof 1 usually'by attaching each rowof blocks to the projecting end of an I-beam.

In my invention, I may suspend a plurality of blocks 4 from thesupporting ceiling 1 by providing apertures 5 in the upper portion ofthe block 4, into which the lower flange of the downwardly projectingbeam 2 is adapted to be positioned. It is to be understood of course,that my invention'is not specifically directed to any pmticular means ofsuspending the refractory root from a supporting roof, since theinventive concept contemplates any of the usual or conventional means ofsuspension.

As a feature of my invention, I may provide a refractory block 4 havingone portion thereof 6 offset, both longitudinally and transversely, toform staggered longitudinal shoulders '7 and 8 and staggered'transverseshoulders 9 and 10. By the provision of a block of this shape thetransverse joints between adjacent blocks are broken, as shownbest at 11in Fig. 1. The provision of a broken joint of this type in itself tendsto prevent the passage of furnace gases from the combustion chamber ofthe furnace to the air space 3, and in addition, likewise prevents thepassage of air from the space 3 to the combustion chamber. To furtherimpede the progress of gases passing from the combustion chamber to theair space 3, or vice versa, I may provide a packing 12 of asuitablematerial such as asbestos base cements, infusorial earth, or the like,in the transverse apertures formed between the upper longitudinalshoulder 7 of one block, the lower longitudinal shoulder 8 of anadjacent block, and the sides which form the joint 11.

In addition to breaking the transverse joints formed between the ends ofadjacent blocks 4, the longitudinal joints may also be broken as shownbest at 13 in Fig. 2, and by the provision of the staggered shoulders Qand 10 longitudinal apertures are provided which may be filled with asealing material- 14 similar to the material 12. In this manner the fourjoining edges of each of the blocks are provided with a seal 12 and 14which prevents any possibility of gases passing through the junctures ofadjacent blocks.

- The feature of my invention of sealing junctures of adjacent blocksmay also be applied to a suspended wall construction. By referringparticularly to Figs. 3, 4, 5 and 6, 15 indicates a 811i?- porting wallconstructed of a material similar to roof 1. Brackets 16 may be fastenedto said wallhymeansofbolts 17 ortheliketheshanhs of which are adapted tobe imbedded in said wall. Oneendoi'thebracketsifirnayterminateinahook-like member 18 which may be adapted to support the refractory block19; said block being provided with a projection 20 adapted to engage themember 18.

One portion of the block 19 may overlap the remaining portion thereofproviding longitudinal shoulders 21 and 22 at each end of said block.

In addition, the overl pped portion of the block 19 may be'oifset withrespect to the portion of the block, forming transversely extendingshudders 28 and 24, said shoulders being staggered with respect to eachother. To join adjacent horizontal rows of blocks 19, auxiliary insertblocks 25 may be positioned between said adjacent rows as shown best inFig. 4. One portion of the blocks 25 may be offset with respect to theremaining portion thereof forming shou1-; ders 26 and 27. j

In laying the blocks 19 and 25 to form a suspended refractory wall,transverse apertures are provided between shoulder 26 of the block 25and shoulder 22 of the block 19 and also between shoulder 27 of theblock 25 and shoulder 21 of the block 19. These apertures may be filledwith a packing material 28 similar to that used in the suspended ceilingat 12 and 14. It can readily be seen that the junctures between blocks25 and blocks 19 are broken and said broken joint is sealed by thepacking material 28. In addition to sealing the junctures between blocks19 and blocks 25, the longitudinal juncture between adjacent blocks 19may also be sealed, said sealing material being disposed in aperturesformed by the transversely extending shoulders 23 and 24 of adjacentblocks 19. This construction is shown particularly at 29 in Fig. 5.

It is to be understood that my invention broadly contemplates thejoining ofadjacent refractory blocks, said surfaces of juncture beingsealed by a suitable sealing material to prevent the passage of gasesthrough said junctures. -It is also to be understood my invention issusceptible of being carried out by using a plastic material or by usingblocks which may be inserted in the apertures formed by the overlappingportions of the various refractory blocks. My invention may be used insteam generating furnaces, cracking stills, 'ovens, kilns, or ingeneral, in any installation wherein it is desirable to insulate acombustion or a heating chamber.

I claim as my invention:

1. A refractory lining for furnaces or the like which comprises, aplurality of refractory blocks having portions thereof offset withrespect to remaining portions, forming shoulders on each of said blocks,a shoulder of one of said blocks being shoulders on each of said blocks,one of said shoulders being staggered with respect to another of saidshoulders to form apertures between the shoulders of adjacent blocks,and a packing material inserted in said apertures.

3. A refractory block for a furnace wall construction having a portionthereof offset with respect to the remaining portion, forming shoulderson said block, one of said shoulders being staggered with respect toanother of said shoulders to form apertures between the shoulders ofadjacent blocks when laid to form a wall and a packing material insertedin said apertures.
